The free edge of the of Figure 1; screen 21. is connected with the longitudinal tom of the window frame, a transversely elongated box-like casing 24: being formed below the sill to receive the roller and screen rolled there-on. As clearly illustrated in Figure-5, the side rails 11 of the Window frame are formed with inwardly cut grooves in which the longitudinal side edges of the screen are reciprocated. The lower screen is also connected with a strip 22 arranged for detachable connection with the lower edge of thelower, window sash for intermittent connection with the sash. Referring in particular to Fig. 6 it should be noticed that the outerlongitudinal-edge of the attaching strip 22 is forced upwards against the bottom of the sash 16, due to the strip 22 pivoting about i the ear of the bracket 23 and pin 18 as an axis, this pivoting being accomplished by the weight of the screen material, which is attached to the inner edge of the strip. In this manner the opening between the strip 22 and sash 16 is closed.

In use, the free edges of the upper or lower screens 21 may be securely connected with the corresponding edges of the window sash, by inserting the ear of the bracket 23 of the 7 connecting strip in the recess formed in the space for the same.

sash and slidably inserting the pin 18 to lock the-ear in position. When the upper sash is lowered, the screen will be pulled clownward-1y so as to cover the window opening and prevent the entrance of insects. Similarly, elevation of the lower sash will lift the lower screen and cover the lower window opening. Furthermore, during the colder seasons of the year the screens 21 can be disconnected from the sashes and will be retained in rolled position at the upper and lower portions of the window frame so as to be well protected from the elements. During the warmer seasons, when insects are prevalent, the connecting strips 22 are attached to the rails of the sashes as previously indicated so that slidable operation of the sashes will automatically cause the screens to cover the opened portionsof the window and prevent the entrance of insects.

This construction obviates the necessity of removing screen frames which may be attached to the window frame at different seasons of the year and maintaining a storage Furthermore, my improvedscr'eens will only be exposed when the window is opened so that the life of the screen will be greatly prolonged.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes as to the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim: 7

1. The combination with a lower window sash having a bottom rail formed at its longitudinal center with a vertically extending recess intersecting a horizontally extending bore provided withlocking pins, of an attaching strip of slightly less width than said rail, a bracket fixed to the center thereof, and having an ear extending into the said vertically extending recess, said ear being slightly longer than the depth of said recess, and engaged by the locking pin, and screen material attached to the inner longitudinal edge of the attaching strip, so that the weight of the screen material pivots the strip to cause the outer longitudinal edge to engage against the bottom of the bottomrail.

2. The combinationwith the lower sash of a window frame having a recess in the bottom thereof and a bore in the side communicative with saidrecess, of an attaching strip disposed below said sash, said strip being adapted to turn slightly .in the frame, a bracket comprising an eye on said strip adapted to fit into said recess, the eye portion of said bracket being slightly longer than the depth of said recess, a bolt disposed through said bore into said recess and engaging said eye, said attaching strip being free to be pivoted relative to said sash, and a screen attached to the inner edge of said attaching strip adapted by virtue of its weight to hold said attaching strip'at an inward and downward inclination to said sash for causing the outer edge of said strip to engage said sash to close the gap therebetween.

In testimony whereof I have aflixed my signature.

ADOLPHE BRIERE.
